Abstract

The cereal aphidRhopalosiphum padi has previously been found to be a low quality prey for a range of generalist arthropod predators. The aim of this study was to reveal, using food consumption experiments whether this applies to other cereal aphids. The question of whether predator feeding capacity increased when several aphid species were offered relative to a single aphid species was also addressed by measuring food consumption on a mixed aphid diet relative to single aphid diets. Food consumption by five carabid beetles of the three cereal aphid speciesRhopalosiphum padi, Sitobion avenae andMetopolophium dirhodum was determined relative to fruit fliesDrosophila melanogaster and the collembolanIsotoma anglicana. Feeding rate was measured as food consumption over 24 hour both for previously satiated and beetles starved for 7 days. Generally the largest aphid consumption was ofM. dirhodum and the lowest ofR. padi, withS. avenae in between. The mixed aphid consumption experiments did not reveal a higher feeding rate on mixed aphid diets relative to single aphid diets. The results indicate low preference forR. padi andS. avenae.

Consommation comparée de trois espèces de pucerons des céréales et d’autres types de proies par des carabes

Résumé

Sur la base d’études préalables, le puceron des céréalesRhopalosiphum padi est considéré comme une proie de faible qualité pour une gamme d’arthropodes prédateurs généralistes. L’objet de cette étude était de montrer par des essais de consommation alimentaire si c’était également le cas pour d’autres pucerons des céréales. La question de savoir si la consommation d’un prédateur augmente lorsque plusieurs espèces aphidiennes lui sont offertes en comparaison d’une espèce unique, a été également examinée en mesurant la consommation alimentaire sur un mélange de pucerons par rapport à des nourritures aphidiennes monospécifiques. La consommation alimentaire de cinq espèces de carabes sur trois espèces de pucerons des céréalesR. padi, Sitobion avenae etMetopolophim dirhodum a été comparée à à leur consommation sur des mouches des fruitsDrosophila melanogaster et le collemboleIsotoma anglicana. La consommation de nourriture en 24 h a été mesurée à la fois pour des carabes préalablement rassasiés et pour des carabes privés de nourriture pendant 7 jours. En général la consommation la plus élevée était surM. dirhodum et la plus basse surR. padi, la consommation deS. avenae étant intermédiaire. L’essai portant sur la consommation de pucerons mélangée n’a pas montré de différence de vitesse d’alimentation sur des pucerons mélangés que sur des nourritures monospécifiques. Les résultats montrent un choix moins fréquent deR. padi etS. avenae.
